Theory and Evidence on the Relationship between Ownership Structure and Capital Structure

Agency theory embeds the influential relationship that exist between managers and shareholders of firms. This relationship has the potential to influence decision-making in the firm which in turn has potential impacts on firm characteristics such as firm value. Prior evidence has demonstrated an association between ownership structure and firm value. This paper extends the literature by proposing a further link between ownership structure and capital structure. Using an agency framework we argue that the distribution of equity ownership among corporate managers and external blockholders has a significant relationship with leverage. The paper tests four hypotheses that explore various aspects of this relationship. The empirical results provide support for a positive relationship between external blockholders and leverage, a curvilinear relationship between the level of managerial share ownership and leverage and finally, the results suggest that the relationship between external block ownership and leverage varies across the level of managerial share ownership. These results parallel and are consistent with the "active monitoring hypothesis", "convergence-of-interests" and the "entrenchment" hypotheses which have been proposed in a different context.
